This project mainly explains a set of big data statistical analysis platform which is applied in Internet e-commerce enterprise, using Java, Spark and other technologies, and makes complex analysis on the various user behaviors of e-commerce website (Access behavior, page jump behavior, shopping behavior, advertising click Behavior, etc.). Use statistical analysis data to assist PM (product manager), data analyst, and management to analyze existing pr

The installation of Spark is divided into several modes, one of which is the local run mode, which needs to be decompressed on a single node without relying on the Hadoop environment. Run Spark-shell Local mode running Spark-shell is very simple, just run the following command, assuming the current directory is $spark_home $ master=local $ bin/

Spark is rolling a storm in the field of data processing. Let's take a look at some of the key tools that have helped Spark's big data platform through this article.Spark Eco-system sentient beingsApache Spark not only makes big data processing faster, but also makes big data processing easier, more powerful, and more convenient. Spark is not just a technology, i

Spark standalone cluster is a cluster mode in the master-slaves architecture. Like most master-slaves cluster clusters, there is a single point of failure (spof) in the master node. Spark provides two solutions to solve this single point of failure problem: Single-node recovery with local file system) Zookeeper-based standby Masters (standby masters with zookeeper) Zookeeper provides a leader election m

Spark is a cluster computing platform originating from the University of California, Berkeley, amplab. It is based on memory computing and has hundreds of times better performance than hadoop. It starts from multi-iteration batch processing, it is a rare and versatile player that combines multiple computing paradigms, such as data warehouses, stream processing, and graph computing. Spark uses a unified tech
